Specification of Letters Patent.

Application filed July s, 1914, Serial No. 851,378. 1

To all 'QCILOY'IZ it may concern Be it known that 1, Emma A. CLARK, acitizen of the United States, residing at .l oliet, in the county ofF/Vill and State of Illinois, have'invented'certain new and usefulImprovements in Dough-Molding M-achines, of which the following isaspeclfi cation. H 1 j The present invention has reference to doughapparatus, and more particularly to that type of molding apparatus inwhich the dough is fed between a pair of moving elements, in sheet orother form, and rolled thereby into balls or loaves. In apparatus ofthis type, the two co-acting rolling elements are usually arranged insuperposed relation, and the upper one is so mounted as toenable it tomove upward under the action of the dough, thus permitting the latter topass between it and the lower element. In actual practice the pieces ofdough should follow each other very closely through the apparatus, butwith the ordinary construction of apparatus, it. is extremely diflicult,if not impossible, to obtain satisfactory results for the reason thatthe upper element on its return or downward movement, must necessarilyrebound after having struck the lower element, and

in consequence the succeeding piece of dough, instead of being properlyrolled, is

' proved means or devices whereby the movable upper element is stoppedimmediately on completing its down-stroke, thus insuring its retentionin correct position to act in conjunction with the lower element, uponthe next piece of dough. r

An embodiment of the invention is illustrated in the accompanyingdrawing, in

which: V

Figure 1 1s a side elevation showlng the attachment in use; and Fig. 2is an enlarged vertical section on line 2-2, of Fig. 1.

present purposes to statethat the apparatus includes a'lower, faced'orcovered roller 1', mounted on a horizontal shaft 2, which rotates in jacounter-clockwise direction, and

an upper roller 3,'having its trunnions 4 Patented Feb. 15, 1916.

supportedin the looped or slotted ends 5 of i the side members 6 of aframe" which is mounted toswing in a vertical plane about a, horizontalaxis or fulcrum that is constituted by a shaft or rod 7; The roller 3has its axis arranged slightly in front ofthe shaft 2, whereon roller 1is mounted, and

is engaged by a belt 8, whichpasses therearound, the belt and the saidroller 1 being driven in any desired manner andthe latter forming withthe upper roller 3, the two zoo-acting rolling elements previouslyreferred to. So-far asfthe operations of this part of the apparatusisconcerned it maybe stated that the roller end of the belt 8 is normallypressed against the covered peripheral surfaceof the roller 1, and'thatthe dough is fed, by any means preferred, 7

and in pieces of suitable size and shape, be

tween the said rollers at the lower or rightof rotation of the upperroller being of course, opposite to that of the lower roller.

The pieces ofdough thus engaged are each rolled up into the form ofballs or loaves,

and as the rolling action, continues, the tendency of the upper rolleris to rise, carrying' with it the supporting frame and belt, and thusultimately permitting the roller-up lump of dough to pass between it andthe lower roller. When the said lump has passed between the rollers, asjustexplained; the upper roller drops back to its former position, andit is to avoid the resultant rebound with its objectionable consequencethatthe locking means about to be described is provided,the lockingaction taking place automatically immediately after each fall of.

the upper roller; For this purpose,there is 7 provided a movable member9, here shown as in the form of a headed pin or stud, which i isintermittently operated by. a suitable im pact element" or hammer 10 andwhich coacts with a fixed lug, shoulder or like projection 11,.carriedbythe'loop end of the adjacent frame member 5.

In the construction illustrated, the headed stud .is 'slidably mountedina transverse re- .cess 12, formed in the upper arm ofan an:

there is also connected theabove-mentioned hammer. This hammer haspreferably the shape of a bell-crank, one of its arms extending upwardlyand having an enlarged terminal head 15, which is disposed directlybehind the stud head, While its other arm extends horizontally, orapproximately so, and terminates in a head 16 that is disposeddirectlybeneath the projection 11. The hammer itself is pivoted at itsapex on a pin 17, attached to the above-mentioned bracket arm. Thearrangement of parts is such therefore, that when the upper roller,after having been raised, has started to drop, the projection 11 willstrike against the head. 16 of the horizontal arm of the hammer, therebyrocking said hammer about its pivot 17 and causing the head 15 of .itsvertical arm to strike sharply against the stud-head. This blow resultsin the stud being driven forward a distance sufficient to causeits endto extend over the projection 11,.thus holding the frame for an instantand consequently stopping the rebound ofthe roller. The

next instant in which the frame rebounds;

from the member 9, allows this suspended member, freedom to fall againstthe bell crank and below the travel or this frame or projection 11. Thepin then drops back against the bell crank and the frame sets in ingelements, and a rising-and-falling frame carrying one of them; of aprojecting mem.
